FI RE-'PLACE GRATE.

SPECIFICATION formingppart of Letters Patent No. 254,062, dated February 21, 1882. Application filed June 22, 1881. (No model.)

sylvania, have invented or discovered a new and useful Improvement in Fire-Place Grates; and I do lhereby declare the following to be a full, clear, concise, and exact description thereof, referencebein g had to the accompanying drawings, making a part ot' this specication, in which-like letters indicating like parts- Figure l is a view in perspective of a fireplace grate containing my present improvements. Fig. 2 is a view in perspective of certain detached-parts thereof. Fig. 3 is a vertical sectional view et' the front casing, illustrative'ot" the attachments; and Fig. et is a detached view, to an enlarged scale, of a portion of the shaking mechanism.

The present invention relates to certain improvements in fire-place grates having ashaker and a close fender or ash-pit front, whereby the agitato'rs are always brought to a horizontal position after the shaking is done. An air-supply is provided to insure a good combustion, and the removable parts are conveniently, easily, and cheaply secured in place.

For convenience of illustration I have shown my improvements as applied to what is sometimes known as the Wellman grate; but I do not intend thereby to limit myself thereto, but include the use of the features claimed in their application to all nre-place grates or stove-grates for which they are suitable.

The lire-basket as represented consists, in connection with suitable back and end tile, of horizontal grate-bars s s, cast either separately or together in` a common frame, and front bars, a, made in like manner. Between the bars s s, and properly secured on a rotary shaft, as is usual in the art, I arrange the shaker leaves or blades c c, and provide for operating the same by a socketed stem, c, piv- Oted at its inner end, as at c3, and by theusual connections c e2 to an arm on the shakershaft. In order to secure a highly ornamental appearance and excludeashesmost effectually from the room, I make the lower front aclose, as indicated by fender b and plates b' b2.

In the plate b', at a point direct-ly in front of Athe socketed stem e, and of a length equal to the lateral motion ofthe stem, in doing the a short projection or teat, a2, made ou'the shaker-handle at such distance from the end that when the handle is inserted the teat n2 may be moved laterally to and fro behind the plate b', as a consequence of which the handle cannot be removed until the teat a2 comes opposite the notch/i', and then the blades c will be in the position described. Hence they cannot be left tilted up, as illustrated in Fig. 2, in which position they are liable to be burned out more rapidly than is necessary.

In applying my present improvements to a Wellman grate, in which the lire-basket is set back, it is usual to insert an enameled horizontal plate directly in front of and on a level with the horizontal grate-bars; but I make this plate, as shown at d, of' ornamental openwork, somewhat as is common in hot-air-register coverings. The openings in this plate may Vbe ot' any desired number, size, or arrangement, but should be such as to supply the necessary air tothe fire-basket from beneath. Hence, as the draft from these openin gs must necessarily be downward, and as the front is close, I prevent eectually the escape of ashes and dust into the room.

As one convenient way of supporting the plate d and keeping itin place, I make the vertical side plates, m, each with rest-lugs o and a slotted clamping-lug, o. The ends of the plate d are then rested on the lugs o and clamped in place by bolts and nuts fr, which pass through the plates and into the slots of the lugs o', as illustrated in Fig. 3. I claim herein as my invention- 1. rIhe fore plate, b', having slit t' and notch in combination, by boil'I and nutw, with fore -xo plate, d, substantially as set forth.

In testimony whereof I have hereunto set my hand.
